  Claims 1–6, 8–10, 15, and 16 are unpatentable as anticipated by Grupp ’483; claims 11, 12, and 14 were not shown unpatentable because Grupp ’483 is not prior art to them.

  • BurdenNot shown unpatentable

    “We agree with Patent Owner. “[A p]etitioner may not submit new evidence or argument in reply that it could have presented earlier, e.g., to make out a prima facie case of unpatentability.” Consolidated Trial Practice Guide5 73; see also 37 C.F.R. § 42.23(b). Here, Petitioner’s breadth challenge to the written description support for the genus of “the metal oxide of the interface layer comprises an oxide of 5 Consolidated Office Trial Practice Guide (Nov. 2019), available at https://www.uspto.gov/about-us/news-updates/consolidated-trial-practice-guide-november-2019. titanium” recited in claims 6, 8, 10, 11, and 14–16, was part of Petitioner’s prima facie case, which could have, and should have, been presented with the Petition. Thus, Petitioner could not properly wait until its Reply to specifically challenge the description support for the breadth of that class in the pre-2011 priority applications. See Henny Penny Corp. v. Frymaster LLC, 938 F.3d 1324, 1330–31 (Fed. Cir. 2019); Intelligent Bio-Sys., Inc. v. Illumina Cambridge Ltd., 821 F.3d 1359, 1369–70 (Fed. Cir. 2016); Ariosa Diagnostics v. Verinata Heath, Inc., 805 F.3d 1359, 1368 (Fed. Cir. 2015). Accordingly, we will not consider the breadth challenge to a metal oxide comprising an oxide of titanium that Petitioner presented for the first time in its Reply. As for the breadth challenge presented in the Petition—that the pre- 2011 priority applications do not describe the breadth of the class of metal oxides, that challenge is inapplicable here because claims 11, 12, and 14 narrow the recited class to comprising an oxide of titanium, which is a far narrower class. Dr. Schubert provides examples of numerous metal oxides that do not comprise oxides of titanium. Ex. 1022, Schubert Decl. ¶ 94 (hafnium oxide and zirconium oxide); Ex. 1053, Schubert Reply Decl. ¶¶ 18, 19 (see the compounds identified in that paragraph beyond titanium dioxide), 20. Petitioner does not dispute that the pre-2011 priority applications disclose a species within the scope of the recited genus. Pet. 18–22. To the contrary, Petitioner relies on one of the pre-2011 priority applications (Grupp ’483) as disclosing a species (with TiO2) as proof that claims 11, 12, and 14 are anticipated. See id. at 40–44. Thus, we determine that Petitioner has not proven that the pre-2011 priority applications fail to describe the genus of the metal oxide of the interface layer comprises an oxide of titanium. Therefore, Petitioner has not proven that Patent Owner is not entitled to the benefit of the pre-2011 priority applications for claims 11, 12, and 14 due to a lack of written description support. Accordingly, Petitioner has not proven that Grupp ’483 is prior art for those claims.” slip op. at 27

    “2. Analysis We agree with Petitioner that the pre-2011 priority applications do not describe the recited genus. To support a claim to a genus, a specification must disclose “either a representative number of species falling within the scope of the genus or structural features common to the members of the genus so that one of skill in the art can ‘visualize or recognize’ the members of the genus.” Ariad Pharms., Inc. v. Eli Lilly & Co., 598 F.3d 1336, 1350 (Fed. Cir. 2010) (en banc). Here, the recited genus is an interface layer comprising a metal oxide. Ex. 1001, 18:45–52. It is undisputed that the only species the pre- 2011 priority applications disclose is TiO2, as set forth in the following passage: Two other properties of the dielectric deserve mention. First is the property of the height of the barrier compared to the semiconductor conduction band (for electrons). In making the barrier thinner than a silicide barrier, the tradeoff may be a higher tunnel barrier (e.g., 2 eV for nitride, compared with about half the gap of 0.6 eV for silicide). Spacer layers may be used with lower barriers (e.g., TiO2 has a barrier of less than 1 eV). Nevertheless, even with the higher barrier to electrons, the present inventors have determined that the resistance can still be one hundred times lower than a contact to silicon with a silicide barrier. Id. at 18:1–11 (emphasis added). The pre-2011 priority applications incorporate by reference U.S.” slip op. at 17

Claim 1 Petitioner argues that Grupp ’483 discloses an electrical junction, citing Grupp 483’s disclosure that “the present invention provides an electrical junction.” Pet. 27 (citing Ex. 1021, Grupp ’483, 3:44–47). Petitioner further argues that Grupp ’483 discloses a region in a semiconductor substrate by describing a source or drain of a transistor. Id. at 28 (citing Ex. 1022, Schubert Decl. ¶ 110). According to Petitioner, Grupp ’483 discloses a metal electrical contact to said region by describing “an electrical device in which an interface layer is disposed between and in contact with a metal and a semiconductor.” Id. (quoting Ex. 1021, Grupp ’483, 4:21–23) (emphasis omitted). Petitioner asserts that Grupp ’483 discloses “said region being electrically connected to said metal electrical contact through said interface layer” by describing “the present invention provides an electrical device in which an interface layer is disposed between and in contact with a metal and a semiconductor and is configured to depin the Fermi level of the semiconductor while still permitting current flow between the metal and the semiconductor . . . .” Id. at 29 (quoting Ex. 1021, Grupp ’483, 4:21–26) (emphasis omitted). Petitioner further argues that Grupp ’483 discloses “said interface layer comprising a metal oxide and a semiconductor oxide” by describing an interface layer that includes (1) a passivation layer, which can be a semiconductor oxide; and (2) a separation layer, which can be titanium dioxide, a metal oxide. Pet. 29 (citing Ex. 1022, Schubert Decl. ¶ 114). Petitioner further asserts that Grupp ’483 discloses “being in contact with said region in the semiconductor substrate and said metal electrical contact” by describing “an interface layer is disposed between and in contact with a metal and a semiconductor.” Id.

Ex. 1101, 3:36–41. In view of this definition in the Specification and the parties’ agreement in pre-institution briefing, we construed the phrase “depin a Fermi level of the metal electrical contact in the vicinity of the junction” as “passivate the semiconductor surface and reduce the effects of metal-induced gap states in the semiconductor” in our Institution Decision.

    “Taken in context, we agree with Dr. Schubert that an ordinarily skilled artisan would have understood Goodnick to refer to Al2O3 as a distinct layer. Ex. 1126, Schubert Decl. ¶ 85; Ex. 1173, Schubert Reply Decl. ¶ 86. Referring to Fig. 8(a), Goodnick states that in an unheated sample with an air grown oxide “[i]t appears that Si has diffused into the Al and collected at the Al2O3-Al interface at the surface. No buildup of Al2O3 is seen at the Al- Si interface.” Ex. 1121, 5. Noting that Fig. 8(b) is a profile of an unheated sample with 30Å of SiO2 at the interface, Goodnick states “[i]n contrast to the air exposed sample, an Al2O3 layer exists at the Al-SiO2-Si interface.” Id. Petitioner notes that, on cross-examination, Dr. Goodnick acknowledged (i) that the Al metal layer would diffuse into the SiO2 interface layer and reduce the portion of the SiO2 layer nearest the Al layer to Al2O3, (ii) that once the Al2O3 layer forms, it would be difficult for aluminum atoms to diffuse through the Al2O3 layer to continue reaction with the SiO2 layer, and (iii) because the reaction is self-limiting, a portion of the original SiO2 layer would remain once the reaction forming the Al2O3 layer stopped.

  • Disclosure Requirements (§112) › Written description (Ariad)Not entitled to earlier dateDecided for petitioner

    “mental steps that an ordinarily skilled artisan theoretically might have taken after reviewing the minimal disclosure in the ’423 patent. The ’423 patent does not discuss any properties of metal oxides (other than the lower barrier of the metal oxide TiO2) or design considerations concerning the selection of particular oxides to use in the claimed structure, particularly in the context of MIGS separation. Dr. Kuhn cites very little, if any, evidence to support her testimony regarding the knowledge of an ordinarily skilled artisan. Thus, we do not credit this analysis as showing that an ordinarily skilled artisan would have found that the inventors of the pre-2011 priority applications possessed the recited genus. See Ariad, 593 F.3d at 1352 (a description that merely renders the invention obvious does not satisfy the written description requirement); PowerOasis Inc. v. T-Mobile USA, 522 F.3d 1299, 1306 (Fed.

Thus, claims reciting the metal oxide interface layer and Group IV semiconductor are anticipated under In re Slayter, 276 F.2d 408, 411 (CCPA 1960) (“It is well settled that a generic claim cannot be allowed to an applicant if the prior art discloses a species falling within the claimed genus; in other words, whatever would infringe if subsequent will anticipate if prior.”) and In re Gosteli, 872 F. 2d 1008, 1010 (Fed.

Nonetheless, on the full record before us, we find that our identification of the level of ordinary skill in art from the Institution Decision as well as Patent Owner’s option (b) are supported by the prior art of record, the ’474 patent, and the opinions of Drs. Subramanian and Steer (which, as discussed above, recognize that additional work experience can compensate for the lack of a formal degree). Accordingly, we modify our preliminary finding to include the specifics from option (b) of Patent Owner’s proposal. Thus, we find that one of ordinary skill in the art would have at least a bachelor’s degree in electrical engineering or a related subject and two or more years of experience in the field of RF circuit design, or at least five years of work experience and training in the design and development of RF circuits and/or systems.

See Vivid Techs., 200 F.3d at 803. sampling Although claim 1 does not recite “sampling” expressly, the post- institution briefs make clear that the parties agree that claim 1 and its dependent claims require sampling. In particular, Patent Owner contends, (1) “the ’474 patent pertains to a technique called sampling, which involves the use of a ‘switch’” (PO Resp. 2); (2) “all of the challenged claims are directed to a sampling system and, in particular, an energy sampling system (also known as an energy transfer system)” (id.); and (3) “[t]he challenged claims only cover energy sampling and the use of switches” (id. at 20). In its Reply, although Petitioner disagrees with Patent Owner’s interpretation of the claims as limited to energy sampling (i.e., energy transfer systems) (Pet.

Resp. 9–10. We agreed with Patent Owner that the specification’s description of a single length indicator that conveys both types of information and the arguments made during prosecution that the claims required a “single LI” or “the same length indicator” to include both types of information were sufficient to support a construction that required a single length indicator to include both pieces of information. See Decision 9. Although it did not propose a construction in the Petition, Petitioner now argues that “the claim language uses the indefinite article ‘a’ to modify ‘length indicator’” and that “[p]recedent is well settled that ‘an indefinite article ‘a’ or ‘an’ in patent parlance carries the meaning of ‘one or more’ in open-ended claims containing the transitional phrase ‘comprising.’” Pet. Reply 5 (citing KCJ Corp. v. Kinetic Concepts, Inc., 223 F.3d 1351, 1356 (Fed. Cir. 2000)). While we agree with Petitioner that “a” may mean “one or more,” that simply means that the addition of more length indicators would not be excluded from the scope of the claim. Petitioner does not explain, and we do not see, how that affects the meaning of “length indicator” itself and, for the reasons argued by Patent Owner and adopted at institution, we maintain the earlier construction of “length indicator” as “a single length indicator that provides two pieces of information: (1) that a first data octet of the protocol data unit is a first octet of a first service data unit; and (2) that at least one other octet of the protocol data unit is the last octet of another service data unit.” See Decision 8; Prelim.

    “We also observe that, although Patent Owner characterizes this issue as one based on “teaching away” (see, e.g., PO Resp. 3; PO Sur-Reply 15– 16), the argument is not about teaching away because Patent Owner is not pointing us to any specific teaching in the prior art, or elsewhere, that would counsel against the proposed modification. Patent Owner is not arguing that something in the prior art disparages or discourages the use of one bit of an LI as a flag. Instead, Patent Owner is arguing that one of skill in the art would not pursue the Qualcomm approach because to do so would mean accepting other drawbacks that would flow from the use of the flag. In any event, we credit Patent Owner’s evidence that dedicating a bit of the LI for use as a flag would reduce the length that could be represented by the remaining bits of the LI and cause SDUs to be divided into more PDUs. See, e.g., Ex. 2005 ¶¶ 30, 32. However, the record also shows that use of the flag would provide a specific advantage, as described in Qualcomm. See Ex. 1006, 3; Ex. 1007 ¶ 253. This is the motivation advanced by Petitioner which, notably, Patent Owner does not dispute. We conclude that, even if Patent Owner is correct that the proposal in Qualcomm would reduce the permitted PDU size from 128 octets to 64, the change would merely be something a skilled artisan would need to weigh against the advantages that the Qualcomm technique would provide. Patent Owner may be correct that the reduced lengths would, in the end, render the modified system unsuitable for certain applications or for adoption in a standard. That would not, however, make the modification nonobvious, particularly where the exact change proposed in the combination was suggested by individuals working in the field, as evidenced by Qualcomm itself.7 The record shows that at least some of those working in the field, at the time of the invention, believed that the advantages of Qualcomm’s approach would outweigh the reduced lengths.” slip op. at 20

  • BurdenMixed

    “In TS25.322, the value “0000000” is a predefined, special value used to indicate that “[t]he previous RLC PDU was exactly filled with the last segment of an RLC SDU and there is no ‘Length Indicator’ that indicates the end of the RLC SDU in the previous RLC PDU.” See Ex. 1005, 36–37. However, although Qualcomm specifically contemplates implementing its flag scheme by “[r]e-arrang[ing] special LI values as they are now coded on less number of bits” (Ex. 1006, 4), the Petition did not argue a combination that includes modification of the special LIs for the independent claims. Instead, Petitioner relied on Qualcomm’s proposal to modify ordinary LIs that indicate the end of SDUs. See, e.g., Pet. 71–72 (describing and illustrating modification of the LI that identified the end of SDU 1: “[t]he green modified LI indicates that a first data octet of PDU is a first octet of SDU1 and another octet of the PDU is the last octet of SDU1”); Ex. 1007 ¶¶ 261–262. Petitioner’s argument with respect to these claims is thus not consistent with the argument it advanced for the independent claims from which these claims depend. Petitioner cannot reasonably rely on one type of prior art LI as the “length indicator” of claim 1, but then shift to a different type of prior art LI when addressing the very same “length indicator” recited in a dependent claim. Moreover, Petitioner fails to explain how or why the special LI “0000000” that is used to indicate the layout of the previous PDU could reasonably be used to also indicate the layout of the current PDU in which the LI appears. For example, if the previous PDU did not meet the condition identified by the “0000000” special value, then the LI would not appear in the next PDU even if that next PDU had a first SDU that ended in that PDU. For these reasons, Petitioner has not provided sufficient explanation or argument to establish obviousness of claims 6 and 21.9” slip op. at 28

    “Although Patent Owner contends Dr. Goodnick’s declaration did not open the door for general questioning about metal oxides (PO Opp. 2–3), we agree with Petitioner that the proper scope of cross examination includes Dr. Goodnick’s understanding of what constitutes a distinct layer. A primary issue raised by Patent Owner against Petitioner’s challenge that Goodnick anticipates is that, notwithstanding its use of the term layer, Goodnick does not teach distinct layers that are required by the claim. See Section VI.B. One of those layers is a metal oxide layer (Ex. 1101, claim 1), in particular a titanium oxide layer (claim 6). In view of Dr. Goodnick’s checkerboard analogy in his declaration, it was proper for Petitioner to question Dr. Goodnick about the extent of materials in the checkerboard. Both parties argue there may be implications of Dr. Goodnick’s testimony for purposes of infringement litigation. See Pet. Opp. 4–6; PO Reply 3–4. We do not address those implications. The issue before us is whether Goodnick would have taught or suggested to a person of ordinary skill the limitations of the claims, which the parties agree include distinct layers of metal oxide and other semiconductor oxide. See Section VI.B. As Dr. Goodnick testified that his article did not teach such distinct layers, it was proper for Petitioner to explore Dr. Goodnick’s views concerning the composition of a layer during cross examination.

    “Taken in context, we agree that a person of ordinary skill would have understood Goodnick to refer to Al2O3 as a distinct layer.

No buildup of Al2O3 is seen at the Al-Si interface.” Ex. 1116, 953.

Eli Lilly and Co., 598 F.3d 1336, 1350 (Fed. Cir. 2010) (en banc). Here, the recited genus is an interface layer comprising a metal oxide, where the interface layer is configured to provide a specific contact resistivity between a contact metal and a semiconductor of than 1 Ω- μm2. Ex. 1001, 18:37–43. It is undisputed that the only species the pre- 2011 priority applications disclose is TiO2, as set forth in the following passage: Two other properties of the dielectric deserve mention. First is the property of the height of the barrier compared to the semiconductor conduction band (for electrons). In making the barrier thinner than a silicide barrier, the tradeoff may be a higher tunnel barrier (e.g., 2 eV for nitride, compared with about half the gap of 0.6 eV for silicide). Spacer layers may be used with lower barriers (e.g., TiO2 has a barrier of less than 1 eV). Nevertheless, even with the higher barrier to electrons, the present inventors have determined that the resistance can still be one hundred times lower than a contact to silicon with a silicide barrier.

We are not persuaded by Patent Owner’s argument, for two main reasons. First, we do not agree that the cases cited by Patent Owner establish that the enablement requirement is satisfied if one of skill in the art could experiment in accordance with the disclosure to find a practical end of an open ended range recited in a claim. Patent Owner principally relies on Andersen Corp. v. Fiber Composites, but the Federal Circuit in that case affirmed the jury verdict of enablement because “the upper limit of the Young’s modulus of the structural member would lie somewhere between the Young’s modulus of the wood fiber and that of the polymer used in the composition.” 474 F.3d at 1377. In other words, there were two known quantities that provided a fixed range. That is not the case here, where Patent Owner does not point to any such predefined limits.

Here, the enablement challenge for priority is for a lack of enablement of the full breadth of the recited range, and in particular, a lack of enablement of the lower part of the recited range (that which is at or near zero). No party has argued that the upper part of the recited range (just below 1 Ω-μm2) is not enabled by either the priority applications or Grupp ’483. See, e.g., Pet. 20; PO Resp. 1–2; Pet.
